                      Product Overview

                      A3950SLPTR-T is a DMOS full-bridge motor driver. It is designed for PWM (pulse-width modulated) control of DC motors, the A3950 is capable of peak output currents to ±2.8A and operating voltages to 36V. PHASE and ENABLE input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation. Internal circuit protection includes motor lead short-to-supply/short-to-ground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection.

                      • Low RDS(on) outputs, overcurrent protection
                      • Motor lead short-to-supply protection, short-to-ground protection
                      • Sleep function, synchronous rectification
                      • Diagnostic output, internal undervoltage lockout (UVLO)
                      • Crossover-current protection, motor supply current is 6mA typical at (fPWM <lt/> 50KHz)
                      • Output on resistance is 0.35 ohm typical at (source driver, IOUT = –2.8A, TJ = 25°C)
                      • Propagation delay time is 600ns typical at (PWM, change to source or sink ON)
                      • SLEEP input current is 27µA typical at (VIN = 2.7V, TJ = 25°C)
                      • Crossover delay is 500ns typical at (TJ = 25°C, VBB = 8 to 36V)
                      • Ambient temperature range from -20°C to 85°C, 16-pin TSSOP package
